This product has been successfully used as the organic silane coupling agent with multi-functional groups in the rubber industry. It mainly used to enhance the elastic modulus and tensile strength of rubber, remarkably improving wear resistance and compressive performance, at the same time it can reduce the rubber viscosity, save working energy consumption. It is best suitable for polymers containing double bonds and rubbers with hydroxylic fillers in its formula. The suitable fillers include silica, silicate, chalk etc., and the suitable rubbers include NR, SBR, IR, BR, NBR, and EMPD.

Comparing with KH-845-4, it can provide more scorching safety because of its disulfur functional groups which have lower reactivity.
